Data transmission
Data transmission , digital transmission , or digital communications is the physical transfer of data (a digital bit stream ) over a point-to-point or point-to-multipoint communication channel.
Extending TCP/UDP-based protocols to the browser by using WebSocket « Matthias Wessendorf's Weblog
WebSocket is a bi-directional AND full-duplex communication STANDARD to build next generations web applications.The Transmission Control Protocol ( TCP ) is one of the two original core protocols of the Internet protocol suite (IP), and is so ubiquitous that the entire suite is often called TCP/IP . TCP provides reliable, ordered, error-checked delivery of a stream of octets between programs running on computers connected to an intranet or the public Internet. Browsers use it when they connect to servers on the World Wide Web sites, and it is used to accurately deliver email and transfer files from one location to another. Applications that do not require the reliability of a TCP connection may instead use the connectionless User Datagram Protocol (UDP), which emphasizes low-overhead operation and reduced latency rather than error checking and delivery validation.

Transmission Control Protocol
Well, here is another TCP/IP network programming but here we are using GNU C on Linux / Fedora Core platform. This tutorial provides quite a complete discussion presented in graphically manner with working program examples from the very basic networking up to the packet level. You need to have some knowledge and skill in C programming language and also familiar with Linux/Fedora Core platform in order to have a good start. The program examples given include the client and server codes but you can test the client and server codes at the same computer. Don't worry about the GNU C, it still based on the Standard C ( ISO / IEC ).

With few steps, C# code for your TCP protocol will be ready, the structure of any TCP protocol generated by .Net Protocol Builder can be described in the following diagram, please note that the generated code is Multi-threaded server and non blocking client connection. Packets are chunk of data containing your own Fields, Packet ID, Packet Type, Packet Start, Packet End, and some constraints on length, all of these factors are generated automatically by .Net protocol Builder, at the end you will deal with packets as objects with some member variables, these variables are your Fields.

The User Datagram Protocol ( UDP ) is one of the core members of the Internet protocol suite , the set of network protocols used for the Internet . With UDP, computer applications can send messages, in this case referred to as datagrams , to other hosts on an Internet Protocol (IP) network without prior communications to set up special transmission channels or data paths. The protocol was designed by David P.
